Great. But:

In the previous version (Oct. 2012), a record looked like this:
(unpacked file:  8.5 GB)

<http://d-nb.info/gnd/4099395-4>
       a       gnd:Work ;
       gnd:firstAuthor <http://d-nb.info/gnd/118628852> ;
       gnd:geographicAreaCode
 
<http://d-nb.info/standards/vocab/gnd/geographic-area-code#XA-DE> ;
       gnd:gndIdentifier "4099395-4" ;
       gnd:gndSubjectCategory
               <http://d-nb.info/vocab/gnd-sc#12.2p> ;
       gnd:languageCode <http://id.loc.gov/vocabulary/iso639-2/ger> ;
       gnd:oldAuthorityNumber
               "(DE-588c)4099395-4" ;
       gnd:preferredNameForTheWork
               "Der @Sturz" .

In the new version, the same record looks like this:
(unpacked file:  5.9 GB)

Why the difference, and where are these formats documented?
(One little but annoying difference is the presence/absence of the
non-filing indicator in the title field.)

Apart from these, there exists the GND-MARC format. The download would
be a lot more compact in MARC. Why not use this for downloading, or
provide it as an alternative?
